LOCK MEGHANISM.

Application ined April 1o, 1925. serial N. 22,092.

e The present invention relates to a locky mechanism and has for its object to provide improvements in locks, particularly of *the combination type such asare used on safes, vaults and the like. y

A further object of the invention is to provide an improved lock operating or control mechanism embodying a simple, economical and reliable form yof construction capable of beingquickly and easily assembled and applied to a door or closure and being of a nature `whereby the tumblery mechanism will be` rendered inoperative should the exterior control means be broken olf or the operating rod driven in. n l

A further object Aof the inventionfis to provide a combination lock and control means therefor embodying one or more units which can be separately constructed and subsequently connected with adooror closure in a comparatively short time and which Will be readily detachable and adapted for application to doors or closures of different sizes for thicknesses.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being vpointed out in the claims at the end of the specification.

In the embodiment of the invention illustiated inthe drawings I have shown a door inside thereof.

or closure `l0 ywhich maybe that of a safe or vault having any suitable lock or ,locking mechanismen the inner face thereof, preferably a permutation` or combination lock u of any well known design, including a housing or casing 1l 4suitably connected with the closure by means accessible only from the The closure is vprovided with an opening` l2 of relatively `large size for accommodating the l connecting means between the lock properland thejcontrol means therefor on the outer tace of theclosure. The connecting means in the present instance comprises a ltubular member 13, connectedy with the lock housing or casing ll in any suitable manner, preferably by being sleeved upon an extension 14 thereof as indicated by dottedlines in Figure l tion of tlie'inetal of the tubular member into a recess formed in rthe extension lil.` The lock and tubular extension` constitute a unitary construction whichcan be applied to the closure as such with suitable fastening means provided for the lock, notshown. The outer endfof the tubular member is threaded and also recessed' orslotted as iii- `dicated at 1.6 and C forms a support for the dial ring or base plate 17, the latter being slidably disposed upon the tubular member and having tongues orprojeetions 18 eX- tending into the slots 16 as shown in Figures 4 and 6. Inner and outer nuts 19 and f 20, respectively, are threaded upon the tubular member to permit the dial ring or base plate to be adjustably positioned thereon, whereby to take care of any variation that Imay occur in the thickness of the doors or closures l0, the base plate being clamped `upon the outer face of the closure by'tight eniiig the nut 20. The construction above described canbe yassembled and applied to the ,closure before applying the lock coiitrol or operating` mechanism whicliwill now and secured thereto by suitable means such .as apin l5, or by driving inwardly a porpreferably threaded to., reccivea groovcd head or "aeta'ting ineinbei' Jf2?) :as rliest shivn in Figiir'es 4 an'd 8, said member b'eing securely held against turning upon the rod by a pin Qgl as shown in Figures et and rlhe headzZ is provided Withaa reduced extension 25 having a bearing within the outer end oi' the tubular member 13 and is kalso provided with a somewhat larger threaded portion 26, the inner end di ivliich has a bearing on the outer end of the tubular member, as shoun in Figure Ll.` Titeh'ead iurthier pr`o`\v"id'e'd ivith oppositely 'disposed grooves or recesses 27 ior a purpose tvhich will hereinatter appear.

A dial 'plate Q8 is provided having the usual gradnations and Acharacters rfor cooperation lwith an indicating niark QJon 'the dial base plate, vvherehj7 anyone entrusted livith the combination may open thefsaie or iaiilt ivhen desired; The base plate 17A is preterabiy dished or recessed as indicated at 30 to receive the dial plate, the latter being s'lidably disposed on the portion 26 ot the head 28 and khaving tongi'ies or projections 3l extending into the grooves' '2T 'so tliatrotation of the head Will eii'e'ct rotation of the dial. The dial ispreferably provided `with 'a finish plate 32 'clainpfed against a Shoulder portion 330i' thehead by thedi'al plate, upon the tightening ot' the nut 2l screived npon the threaded portionfQG of the head. The head also forms a support foi' 'a knobv or hfndle by `ivhich thejwrod 2l is rotated, the knob4 preferably einbodyinga rin'g ot' any suitable material surrounding ythe head and clamped iipon the finish plate 32 by an outer ring 36 vvi'hi'ch 'may be 'constructed of hard rubbercor any other suitable material and which is preferably tinted `or `dron'fed'as shown at 37 'to faciliY tatie gripping andrtnining theflnolo by the operator. The ring 36 is provided with inwardly disposed ribs projecting into th'e grooves 27 of the head to effect rotation of the rod. The rings 35 andfi' are clamped in position by a plate 39 having a threaded member -10 screwed into the head 23 as shown in Figure 4.. The nieinber Li() is prefei'ably slotted at Ll-l to receive a sreivfdriver by which the plate 39 n'iay be tightly clamped upon the ring 36 before the rod Q1 is screwed `within the head, although Asaid plate may be lscreved into position upon for removed from the head by an eXt'e'rio'rojieration if desired. Rotation 'offthe lock control rod 2ll is of course effected by'tnrning the knob or handle in the desired diiecf tion, it being remembered that the inner end of the head is rotatably disposed Within or uponthe oiit'e'r end of the tiibiilar ineinber i8 as above stated.` p

The-rod Q1, head Q3, dial platevQB and knob 'forni a 'cinpi'ete unit lvliieh is constructed and applied as siicliby inserting the rod through the tubular, member into ihenib'er 'Q2 and such o'ili'i' loch "cnt'iol parts as may be desired are inserted upon the rod and secured in any suitable manner, before the cover plate` t3 is. applied to' ithe lock casing, as by a key '12 driven into a keyway to'rin'ed in the end of the rod. Any suitable torni of latch or lock bolt not shown may bie employed in connection with the lock.

From the ,construction ,shoivny it )vill be apparent that it' it atteinptedto ropfen the sfeby breaking oitythe knob and driving in the control rod, operation of the tinnblers cannot be effected since the `ifd and parts thereon forni the only control 'or Operatingmeansforthe tuinbl'e'is. j, j,

While y the construction sho'ivn in tlrejd'razvings atl'ords 'a simple and practical embodiment of the invention it n'ill be nndeistoiid that the different forins offconstrneftin 'and arrangements ot parts shoivn may be modi- .tied to a certainement ivithot departing from the scope or' the invention 'as covered by `the claires.` l,
